The idea that military strength is virtually synonymous with security is deeply entrenched and widely held. But while the threat or use of military force may sometimes be necessary, it cannot keep us as safe as we would be by building relationships that replace hostility with a sense of mutual purpose and mutual gain.

He also considers the practical problems of the transition from military-based security arrangements to &quote;economic peacekeeping,&quote; and the effects of demilitarized security on economic development and prosperity.
